[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0019] like Figure 1 and Figure 2As shown, the present application provides a fastener heat treatment equipment, including a heat treatment box body 1. The heat treatment box body 1 is the existing technology, which provides a relatively closed environment for the heat treatment process of the fasteners, can effectively maintain the temperature stability in the box, and reduce the interference of the external environment on the heat treatment effect. Two protective doors 11 are hingedly connected on one side of the heat treatment box body 1. In addition to closing the heat treatment space to reduce heat loss, the protective door 11 can also block high-temperature radiation and splashes that may be generated during the heat treatment process, thereby protecting the safety of operators.

[0020] like Figure 2 、 Figure 3 and Figure 7 As shown, a discharge assembly 2 is installed in the heat treatment box body 1, and the discharge assembly 2 is used to place the fasteners to be heat treated. The discharge assembly 2 includes two guide rails 21 installed at the bottom of the heat treatment box body 1 by bolts. Guide plates 22 are slidably installed in the guide rails 21. The smooth track design of the guide rails 21 provides a path for the sliding of the guide plates 22, ensuring that the discharge assembly 2 is not easily offset when entering and exiting the heat treatment box body 1. Support plates 23 are fixedly installed on the upper part of the guide plates 22. The support plates 23 serve as a load-bearing structure and are made of aluminum alloy. They can firmly support a large number of fasteners on the discharge part. Support rods 24 are fixedly installed at the corners of the upper surface of the support plate 23, and multiple discharge trays 25 are evenly fixedly installed on the rod body of the support rod 24. The frame structure formed by the support rods 24 can fix the multiple discharge trays 25 in layers, so that the discharge trays 25 are kept at uniform spacing, which facilitates the uniform flow of heat between the layers of fasteners during the heat treatment process, ensuring that each fastener can be heated evenly; A plurality of discharge holes 26 are evenly arranged on the discharge tray 25, wherein the discharge tray 25 is made of high-temperature resistant material and can withstand the high-temperature environment during the heat treatment process without deformation. The provision of multiple discharge trays 25 increases the number of fasteners subjected to a single heat treatment and improves the treatment efficiency. At the same time, the discharge holes 26 are designed with an initial aperture according to the size specifications of common fasteners, which can not only play a preliminary positioning role for the fasteners to prevent them from rolling and colliding on the discharge tray 25, but also allow most of the surface of the fasteners to be exposed to the heat treatment environment to ensure the adequacy of the heat treatment.

[0021] like Figure 3-Figure 7As shown, an aperture adjustment component 3 is installed on the discharge tray 25, and the aperture adjustment component 3 can adjust the effective aperture of the discharge hole 26 to adapt to fasteners of different sizes, without replacing the discharge tray 25, thereby improving the work efficiency of the staff. The aperture adjustment component 3 includes a first mounting bracket 31 fixedly mounted on one side of the lower portion of the discharge tray 25, and a long rod 32 is rotatably connected to the upper portion of the first mounting bracket 31. The first mounting bracket 31 provides a stable support point for the long rod 32, ensuring that these components are not prone to shaking when rotating or subjected to force, thereby ensuring the accuracy of aperture adjustment. At the same time, the rod body surface of the long rod 32 is smooth, and a bearing is installed at the rotation connection portion with the first mounting bracket 31, which reduces the friction resistance during rotation and enables the long rod 32 to rotate flexibly. A first bevel gear 33 is fixedly connected to the long rod 32; A rotating rod 34 is rotatably connected at the central position of the bottom of the first mounting frame 31. The rotating rod 34 is an intermediate carrier for transmitting manual operating force. Its length is reasonably designed to facilitate manual rotation operation to realize control of the aperture adjustment component 3. A second bevel gear 35 that meshes with the first bevel gear 33 is coaxially mounted at one end of the rotating rod 34. The mutual meshing of the first bevel gear 33 and the second bevel gear 35 constitutes a power steering transmission mechanism, which converts the vertical rotation movement of the rotating rod 34 into the horizontal rotation movement of the long rod 32, changes the transmission direction of power, and enables the long rod 32 to rotate smoothly. A rotating disk 341 is fixedly mounted at the other end of the rotating rod 34. The irregular shape of the rotating disk 341 increases the force application area of ​​the operator, making it more labor-saving when rotating the rotating rod 34. A plurality of first one-way threaded cylinders 36 and second one-way threaded cylinders 37 are respectively mounted on the shaft of the long rod 32. A first slide plate 361 is threadedly connected to the first one-way threaded cylinder 36, and a second slide plate 371 is threadedly connected to the second one-way threaded cylinder 37. The first one-way threaded cylinder 36 and the second one-way threaded cylinder 37 are staggered and have opposite thread directions, which can respectively drive the first slide plate 361 and the second slide plate 371 to move in opposite directions, thereby achieving the purpose of adjusting the aperture adjustment portion closer to or farther away from the aperture of the discharge hole 26. An aperture adjustment plate 38 is fixedly mounted on one adjacent end of the first slide 361 and the second slide 371. The aperture adjustment plates 38 are located directly below the discharge holes 26, and the number of the aperture adjustment plates 38 corresponds to the discharge holes 26. The aperture adjustment plates 38 are made of alumina ceramic, and their shape matches the discharge holes 26. When they move directly below the discharge holes 26, they can change the effective passage area of ​​the discharge holes 26, thereby adjusting the position of the aperture adjustment plates 38 to meet the use of fasteners with various diameters. A second mounting frame 39 is fixedly mounted on the other side of the lower portion of the discharge tray 25, and a guide rod 391 is fixedly mounted on the second mounting frame 39, wherein the other sides of the first slide 361 and the second slide 371 slide along the rod body of the guide rod 391 and are symmetrically distributed with the first mounting frame 31, together constituting a support frame of the aperture adjustment assembly 3. At the same time, sliding bearings (not shown in the figure) are installed at the contact portions of the first slide 361 and the second slide 371 with the guide rod 391, further reducing sliding friction, making the movement of the slide smoother, and reducing jamming during the adjustment process.

[0022] Reference Figure 4 and Figure 6 As shown, a distance observation assembly 4 is installed on a single set of second slides 371. The distance observation assembly 4 can intuitively display the moving distance of the aperture adjustment plate 38, helping the operator to control the adjustment amount of the aperture of the discharge hole 26 and ensure the adjustment accuracy. The distance observation assembly 4 includes an adapter plate 41 fixedly mounted on the single second slide 371, and a marking head 42 is fixedly mounted on the lower part of the adapter plate 41. The marking head 42 is triangular, wherein the adapter plate 41 can move synchronously with the single second slide 371 to ensure that the moving distance of the marking head 42 is consistent with the moving distance of the slide, providing a basis for the accuracy of the distance display; Scale lines 43 adapted to the marking head 42 are provided at the bottom of the first mounting bracket 31. The spacing of the scale lines 43 is precisely calculated in millimeters and can accurately reflect the movement distance of the aperture adjustment plate 38. By observing the position change of the marking head 42 on the scale, the operator can intuitively judge the adjustment amount of the aperture of the discharge hole 26, thereby adjusting the aperture to a value that matches the size of the fastener, thereby improving the efficiency and accuracy of the adjustment.

[0023] Working Principle: When in use, the operator first places the fasteners to be heat treated one by one into the discharge hole 26 of the discharge tray 25. The discharge hole 26 plays a preliminary positioning role for the fasteners. If the size of the fastener does not match the initial aperture of the discharge hole 26, the aperture can be adjusted by rotating the rotating disk 341: the rotating disk 341 drives the rotating rod 34 to rotate, and the second bevel gear 35 at the other end of the rotating rod 34 rotates accordingly. The first bevel gear 33 meshing with the second bevel gear 35 drives the long rod 32 to rotate synchronously; Since the first one-way threaded barrel 36 and the second one-way threaded barrel 37 on the long rod 32 have opposite thread directions, when they rotate, they drive the first slide 361 and the second slide 371 to slide in opposite directions along the guide rod 391, thereby driving the aperture adjustment plate 38 closer or farther away. At this time, the adapter plate 41 on the second slide 371 drives the marking head 42 to move. The operator controls the aperture adjustment amount by pointing the marking head 42 to the position of the scale line 43 until the discharge hole 26 is adapted to the size of the fastener. After the adjustment is completed, push the support plate 23 to make the guide plate 22 slide into the heat treatment box body 1 along the guide rail 21, close the protective door 11, and start the equipment for heat treatment. During the heat treatment process, the uniform spacing between the multi-layer discharge trays 25 ensures heat circulation, so that the fasteners are heated evenly. After the treatment is completed and cooled, open the protective door 11, pull out the discharge assembly 2, and remove the heat-treated fasteners.

[0024] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
